Why Is My Cat Drinking a Lot of Water?


Have you noticed your cat drinking a lot of water lately?

Well, every cat is different and each one of them will drink various amounts of water depending on their environmental factors, lifestyle and health condition. For instance, a cat living inside a cool home may not be drinking quite as much as a very active cat who loves to spend too much time outside. Just like us, they will also be drinking more during really hot days or if they have been physically active, but do you know that there are still a lot of other factors that will affect how much your cat drinks? Probably she’s trying to tell you something other than she’s thirsty.

So let’s see the possible causes and reasons below for why some cats seem to drink way too much water.

Why Is Your Cat Drinking So Much Water

Why Is My Cat Drinking a Lot of Water?

1. Did you make any changes to her food diet?

Well, you might be responsible as to why your cat is drinking excessive water lately. Their food diet can highly affect their water consumption.

If you have been feeding your cat with some dry foods and spoiling her with tasty crunchy food, this will make them drink more water as this food can make them thirsty. Dry cat foods only contain as low as 6 to 10% of water while wet or can foods contain as much as 75% of water. This is definitely a big difference! As a result, they will sometimes overcompensate for the lack of water their meals provide.

So if you are feeding your cat with dry foods more than with wet foods, just make sure you try to correct it by adding more wet food to your pet's diet; I'm sure your cat will be able to adjust through time, though we can expect to experience some opposition from our little fur ball for a couple of days.

However, if you notice your cat still continues to keep drinking too much water, I'm afraid this could be a sign of a bigger problem and this is something we should not overlook.

2. Your cat may probably be suffering from kidney disease.

Since cats don’t normally drink plenty of water that some pet owners struggle their way in finding creative ways to encourage their cat from drinking more water, they are at much higher risk of kidney problems and dehydration. There are even reports that say 1 in 3 cats will experience kidney problems in their lifetimes.

So if your cat is already of old age, drinking a lot of water and is frequently urinating even outside the litter box, there’s a bigger chance that she is suffering from this unfortunate disease.

There are still a lot of signs your cat’s kidneys may be failing that you need to learn, so once you start noticing these signs, don’t hesitate to consult your veterinarian and do all kinds of urine and blood test before it is too late.

3. Does your cat have diabetes?

Yes, you heard it right! Your sweet friend can also suffer from diabetes mellitus which could possibly happen when your cat’s body can no longer produce insulin or when it doesn’t use it properly.

You need to pay attention to the signs that include weight loss, increased urination, bigger appetite and of course, excessive thirst.  Cat's increase of water consumption is one of the early signs of diabetes in cats which is normally accompanied with sudden weight loss that will only be replaced with weight gain. This very specific pattern will help you determine whether your cat is suffering from this illness, though this type of diabetes normally happens to males and obese cat.

4. Have you checked if your cat has hyperthyroidism?

Excessive thirst is also one of the symptoms of hyperthyroidism, along with increased shedding, weight loss, increased appetite, hyperactivity, vomiting, and diarrhea. This glandular disorder is very common in cats.

If you begin seeing these signs, don't wait for a second and visit your veterinarian immediately.

How Will You Know If Your Cat is Drinking Water Excessively?

A cat drinking a lot of water than normal which is referred to as polydipsia as well as its consequent polyuria or when the cat that urinates more than usual, are both symptoms that you don’t get to notice often. This is why it is very important that you determine the normal amount of water your cat is drinking every day or else we won’t be able to recognize that something is not going well. You might need to know your cat’s routine and personality to do this.

How Will You Know If Your Cat is Drinking Water Excessively?

How Will You Know If Your Cat is Drinking Water Excessively?

Normally, a domestic cat will intake about 45 ml/kg per day or around 2 to 4 ounces per day. I know that you are wondering by now if there’s a way to know if your cat is drinking more than this standard amount. Well, a veterinarian can actually do a sequence of a laboratory test to study the urine of your cat and evaluate the difference between water intake and the quantity excreted in order to achieve a better diagnosis and recommend the correct treatment.

But there is actually a method that you can try at your home so you can check if your cat is drinking more water than normal. At the beginning of the day, measure the amount of water you put into her bowl then before the day ends, get the amount they drank. Divide this two value by the weight of your cat, if you get a result that is greater than 45 ml per kg. then you might need to contact your veterinarian.

But if you think it would be difficult to keep an eye to your cat's water intake, especially if you have more than one cat which makes it impossible to determine who is eating and drinking what, then you can at least look out for other signs that your cat has been drinking a lot more than normal. These are:

  • Making several trips to the water bowl than normal.
  • Calling for their water bowl to be filled up more often.
  • Frequently drinking from unusual places like ponds or taps, which they haven’t done before.

So there you have it, I hoped I was able to answer your question as to why your cat drinking a lot of water. If you begin noticing changes to your cat’s behavior, you should always bring up any concerns with your vet.
